Apache 访问控制,请教!!

Apache+Win2000,
Apache 只在基础上修改了httpd.conf
设置了AllowOverrude all
用htpasswd在要限制的目录下面生成.htpasswd文件,
同时在要限制的目录下面新建.htaccess文件
内容如下:
AuthName Members Only
AuthType Basic
AuthUserFile D:\Program Files\Apache Group\Apache\htdocs\login\.htpasswd
require user reader
页面请求后,出现http500的错误,

Apache日志记录
[Tue Jun 26 20:23:42 2001] [alert] [client 127.0.0.1] d:/program files/apache group/apache/htdocs/login/.htaccess: AuthName takes one argument, The authentication realm (e.g. "Members Only")
应该如何设置啊??
